ABSTRACT:
Exemplary embodiments of the invention provide a circuit that includes a plurality of projector units to modulate and project light from a light source based on image information, a transmissive screen to which projection images from the plurality of projector units are projected, an image-capturing device disposed in a housing to capture predetermined regions of the projection images projected onto the transmissive screen, a unit image information generating unit to generate image information to be inputted to each of the plurality of projector units, and a unit image information correcting unit to correct the unit image information based on a result captured by the image-capturing device. Therefore, it is possible to perform easily the adjustment process and to further reduce the adjustment time.
